IMPROVEMENT` IN RAG-MACHINES.

Specification forming part of Letters Patent No. 217,100, dated J nly 1,1879; application filed May s, 1879.

To all whom it 'may concern:

Be it known that I, THOMAS VALTER HARDING, of the Tower Works, GlobeRoad, Leeds, in the county of York, Kingdom of Great Britain andIreland, hackle, gill, and pin manufacturer, have invented new anduseful Improvements in Rag-Engines, of which the following is aspecication.

My improvements in rag-engines relate to the steelpin coverings of theircylinders. Such coverings have been made in various ways. One usual planis to make the coverings in wooden segments or lags, into which aredriven steel teeth, tapered by forging, and having their shanks square.In some cases teeth with a ground taper and made of round steel havebeen used; but they are liable to become loose, to fly out in working,and to turn round in the holes when, after the pins have become bent,itis attempted to straighten them, or if their action in workingbereversed. It has been attempted to obviate these evils by the use ofround pins or wires made with nail-heads, or having their roots slightlyattened.

Now, my invention has for its object to produce a steel-pin cover forrag-en gine cylinders so constructed that the pins cannot either iiy outorturn round, as aforesaid. For this purpose I cover the cylinder with acase, cover, or lagging of metal in segments, provided with pins groundor tapered at the ends, and made with round parts, bent or curved, ashereinafter described. The ground or tapered ends or prongs of thesepills I pass through the thickness of said Case, cover, lagging, o r

l segments, so that said bends bear, rest, or

bed against or between the surfaces of the cylinder-body and case,cover, lagging, or segments, as hereinafter described.

Referring to the accompanying drawings, Figure 1 shows, in section, partof a rag-engine cylinder with my invention. applied to it; and Fig. 2 isa sectional view at right angles to Fig. l.

The cylinder-body c is formed with an annular recess, b, or, in otherwords, is of larger diameter at its ends c than at its intermediatepart, Z.

d is an iron case or cover, in segments, surrounding the cylinder-bodya.

c c are round steel pins, ground or tapered at both ends, c* el, bent ate2 into the form of staples, and driven through saidiron case, cover, orsegments d, so that the prongs project outwardly, as at el el, and theconnecting portions or bends e2 are jammed between the cylinder-body aand the metal case, cover, or segments d, which is, or are, fastened (itmay be by screwsf, as shown) to the cylinderbody a.

I `do not, however, limit myself to the use of my improved pins withground or tapered ends el and round, curved, or bent parts e2, incombination with a metal case, cover, or segments, as they may be usedin combination with a case or cover of wood, as shown in Fio. 3, 'wherea is the cylinder-body; d, the case or cover, made of wood in segments,(as already practiced and c e are the round steel pins, ground ortapered at both ends, eI c, bent at e2 into the form of staples, anddriven through said wooden case or cover d.

The bends e2 are pressed or sunk into the wood d so as to be flush withthe inner or back surface thereof 5 or the back of the segment or lagmay be grooved to receive the bends e2 ofthe pins.

It is to be remarked that the advantages of my invention may be to aconsiderable extent realized by the use of halfstaples or pins withcurved ends, or bycuttin g the staples in the line A B, or making themin the form of portions of staples, as shown, to the respect ive sidesof said line A B, so as to produce a curved part, e2, which will bear,rest, or bed against the surfaces of or between the cylinder-body andthe case, cover, or lagging, substantially as and for the purposespecified.

1. As a new article of manufacture, a ragengine-cylinder pin ground ortapered at the ends or end el, and made with a round part, bent orcurved, substantially as described, and shown at c2, for the purposespecified.

2. The combination, with a rag-engine-cylinder body, a, and a metallicor other case, cover, or lagging, d, of steel pins e, ground or taperedat the ends or end el, and made with i surfaces ofl or between thecylinder-body a round parts, bent or curved, substantially as described,and shown at e2, the whole constructed, combined, and arrangedsubstantially in manner speeiiied--that is to say, with the ground ortapered ends o1 of said pins protruding through said ease, cover, orlagging d, and their round, bent, or curved parts e2 bearing, resting,or bedding,` against the and the ease, cover, or'lagging d,.allsubstantially as hereinbefore explained and illustrated.
